PINARES-ASTETE, Franck et al. Long-term survival in patients with stage 5 chronic kidney disease undergoing hemodialysis in Lima, Peru. Acta méd. Peru [online]. 2018, vol.35, n.1, pp.20-27. ISSN 1728-5917.

Objective: To assess the long-term survival of patients with stage V chronic kidney disease that entered a hemodialysis program in Lima, Peru and prognostic variables that affected survival were determined. Materials and methods: We assessed a prospective cohort of 604 patients enrolled in a hemodialysis program (1982-2009) and who were followed-up until December 2015. Survival was studied using the Kaplan Meier curves and comparisons were established using the Log-rank test; according to age, etiology, renal transplantation and period of admission to hemodialysis. Through the Cox regression analysis, prognostic variables of survival were delimited. Results: The mean age ± SD age of the population was 51.95 ± 16.17 years; 43.1% were > 60 years old, and 43.4% were women. The most frequent etiologies were primary glomerulopathy (21%), diabetes mellitus (20%), high blood pressure (12%), and interstitial nephropathy and/or urinary tract obstruction (11%). Survival percentages (95% confidence interval) in years 1, 5, 10, 15, and 20 were 80% (77%-83%); 47% (43%-51%); 25% (21%-29%); 17% (13%-21%), and 11% (8%-14%), respectively. Cox regression analysis identified being elderly and diabetic as unfavorable variables for survival, and having undergone renal transplantation as a favorable variable. Conclusions: Long-term survival is comparable to that found in other studies performed abroad. The lower survival of our patients is related to the following conditions: advanced age, diabetes, and not having the possibility of undergoing renal transplantation. Technological changes during the follow-up period did not significantly modify the survival curves
